Magnetic Differential Gearbox

Model Differential gearbox with Universal joint input. Uses magnets (5mm od, 3mm thick) instead of cog teeth. Bearings are 4mm id, 8mm od, 3mm thick to support the lengths of 4mm carbon connection rods (10 bearings in all). Small packing washers used as required. Transfers very little power, but it's only supposed to be a functional demonstration model
